Specification of Letters Patent.

Patented Apr. 25, 1922.

Application filed December 28, 1920. Serial No. 433,687.

To all whom it may concern:

Be it known that I, BARNETT SHATZ, citizen of the United States, residing at 25 de Mayo Street No. 214;, Buenos Aires, Argentina, have invented new and useful Improvements in a New Type of a Ruler Blotter, of'which the following is a specification.

This invention relates to improvements in rulers and more particularly to rulers having means for absorbing the ink which may flow over the ruling edge of the same.

The primary object of the'present invention is to furnish an ordinary ruler with means for use in absorbing any ink which may flow over the ruling edge, and which may also be used for blotting the lines drawn by the aid of said ruler.

With the foregoing object outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafterdescribed in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims. Referring to the drawing Figure 1 is a top plan view of one end portion of a ruler having my improvements I applied thereto.

Fig. 2 is a transverse sectional view taken on line 22 of Figure 1.

Fig.8 is a longitudinal sectional view- I taken on line 33 of Fig. 1.

V have provided the following improvement;f

In the drawin 8 desi nates an ordinarv an a ruler having a beveled edge 9 terminating in a ruling edge 15. In using a ruler of this ordinary construction for the purpose" of drawing lines and the like, it frequently happens thatthe ink overflows the edge 15 and forms a blot on the paper being ruled. In orderto overcome this disadvantage, I.

On the underside of the ruler I place a sheetor strip-13 of blotting paper,and the front edge 14: of this paper is arranged in close proximity to the edge 15 ofthe ruler, so that any ink flowing over the edge 15 will be absorbed by the blotting paper.

In order to secure this blotting paper to V the ordinary ruler, I preferably place adhesive on one side of the blotting paper to cause the same to adhereto a strip of cloth 10 which is placed on the underside of the ruler 8 and has its end portions 10 folded 12 may be securedinposition by'sliding the same longitudinally of the groove.

From the foregoing I believe that the con- It will be noted that each recess struction, operation and advantages of the invention may be readily understood, and I am aware that various changes may be made in theconstruction illustrated without departing from the spirit of the invention as expressed inthe following claims. I

'1. A ruler having on its upper side and near one end of the same, atransverse groove, a blotting device arranged on the underside of the ruler and having an end member extending around one end of the rulerand ttII'fi-I'lfifiddll'Sdld groove, and a member arranged 1n thegroove and engaging said end member for securing the blotting devicein position. v

2. The combination with an ordinary ruler having. a dove-tail groove in-its upper surface arranged near. oneend of the ruler, and extending transversely across said ruler, a cloth strip arranged on theunderside of the ruler and having an end'portion' extending around one end of the ruler and a engaging said groove,a member arranged in said :grooveand engaging the end portion of the cloth for holding the samein said groove, and a strip of blotting paper secured to said cloth strip and having an edge arranged in close proximity to the ruling edge ofsaid v Y In testimony whereof I have signedmy name to this specification in the presence of" two subscribing witnesses.
